INFANT-CHAIR.

Application filed July 3, 1919.

T 0 all whom it may concern:

Be it known that 1, JOHN STRAITH, a citizen of the United States,residing at Richmond, in the county of Henrico and State of Virginia,have invented certain new and useful Improvements in Infant- Chairs, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

My invention relates to improvements in infant chairs.

The object ofiny invention is to provide an improved device of thischaracter, whereby the chair may be conveniently attached to a table, orother suitable object, so as to support the chair firmly in position forholding an infant or child.

Another object of my invention is to provide an infants chair soconstructed that it cannot be tipped over and thereby injure theoccupant.

A still further object of my invention is to provide a simple, cheap anduseful infants chair of this character, which can be readily attachedfor use or detached and put out of the way when so desired.

In the accompanying drawings- Figure 1 is a perspective view of myimprovement applied to a table.

2 is a vertical central longitudinal sectional view of Fig. 1.

Fig. 3 is a rear elevational view of he supporting bracket.

Referring now to the drawings, 1 repre sents the bottom of a chaircomposed of the hack .2, and arms 3, and arm supports 4-.

No special form of chair is necessary, except one adapted for children.

In the illustrative form here shown, there is attached to each side ofthe seat 1 of the chair and extending outwardly and forwardly therefrom,two elongated supporting bars 5, attached in any suitable manner to thechair bottom.

Cooperating with the supporting bars 5, are two brackets 6, which areattached to the table 7. Each of these brackets is enlarged and isLl-shaped in cross-section. The outer end of the U-shaped bracket isclosed by a depending web or flange 8, which thus forms an opening 9, inthe front end of each bracket into which the supporting bars 5 fit andare adapted to slide back and forth therein. The elongated U-shape ofthe bracket forms an elongated supporting sur- Specification of LettersPatent.

face at the top of the U for the supporting bars, and the sides of the Uform elongated guides for the supporting bars 5, thus holding thesupporting bars against lateral movement in respect to the brackets.From this it will be observed that the elongated brackets and elongatedsupporting bars form a substantial and steady support for the chair inits various positions.

In the form of bracket 6, here shown, its outer end isprovided with twoupwardly eX- tending arms 10 and 11, forming an upwardly extending slot12, which embraces the dependingboard or flange 13, extend ingdownwardly from the top 14:, of the table 7.

Attention is directed to the fact that the front upwardly extending arm10 is short and tapered upwardly, as shown, so that there is very littleof the bracket that is exposed. On the other hand the inner upwardlyextending arm 11 is made relatively heavy and about twice the length ofthe outer arm. A clamping screw 15 passes outwardly from the long armpreferably near its upper end and engages the inner side of thedepending flange 13 of the table 7. This inner arm being thus elongatedis preferably a length equal to the width of the depending flange 13 ofthe table. By reason of this construction there is a long bearingsurface on the depending flange of the table to receive the lateralstrain on the depending flange caused by the weight of the chair and thechild occupying it. Furthermore, the strain caused by the weight of thechair and the child is largely at the top of the long arm which bringsit substantially at the top of the depending flange of the table, thusminimizing the chance of splitting or breaking the depending flangecaused by the strain above referred to.

Attention is particularly called to the fact that the supporting barsare made of a length safely longer than either the leg or arm-reach ofthe child at the table. This prevents the child from pushing the chairso far from the table as to disengage the supporting arms from thebrackets. By this construction there is no necessity for any stops onthe supporting rods, and it enables the chair to be quickly detachedfrom the brackets when not in use, and quickly attached without thenecessity of operating any stops, latches, or locks of any kind.

For the purpose of strengthening and bracing the inner long arm, whichsustains substantially all of the before-mentioned strain, I provide atriangnlarbrace portion 16 between the long arm and the top of theelongated U-shape portion.

Serious accidents have happened to children using the ordinaryhigh-chair caused by the child pushing the chair over'baclc ward. As aconsequence where high chairs are used, it is customary to watch thechild closely to prevent such an accident.

By the use of my above described construction, such an accident cannothappen. The table forms a support which the weight of the child cannottip over; it eliminates all chance of accident and removes the necessityof paying attention to the child to prevent accident while at the table.It also enables the child to be pushed sufiiciently far from the tableto prevent it from meddling with the settings on the table, which is acommon,'dangerous and annoying practice of children.

Having thus described my invention, what.

I claim and desire to secure by Letters Pat out is 1; A childs seat fortables, comprising a seat portion, having a forwardly projectingsupporting member approximately in the horizontal plane of the seat, andof less Width than the width of the seat to provide leg space at theside of the support, and

supporting means comprising a member attachable to a table top, saidattachable member having a longitudinally extending supporting way toreceive the chair supporting member, the longitudinal supporting waylocated in a horizontal plane out of line with the top of the table,whereby the supporting member may be moved in and out in respect to thetable top.

2. The combination of a childs seat having a forwardly projectingelongated support approximately in the horizontal plane of the seat, theelongated support of less width than the width of the seat to provideleg space at its side, and a supporting member detachableto a table top,the supporting member having a longitudinally elongated supporting-wayfor the elongated seat support, the elongated way located in a hori-Zontal plane out of line with the table top whereby the seat support maymove in and out in respect to the table top, the said seat supporthaving a length exceeding the arm or leg reach of the child, for thepurpose described.

3. The combination of a childs seat having two forwardly andhorizontally projecting parallel. rod supports and two supportingmembers, each of saidmembers having a clamp for attachment to a table orthe like and constructed to receive and support the outer end of thesaid projecting seat supports.

4. The combination of a childs seat having two seat supporting rodsprojecting forwardly and horizontally therefrom and two supportingmembers of an elongated in- .verted U-shape, the outer end of each U-shaped member closed by a wall forming a support for said seat rods, andtwo arms projecting from the outer end of the U- shaped members andforming a clamp for attachment to a table or the like.

In testimony whereof I hereunto affix my signature.

JOHN STRAITH.
